SAFETY-BOX FOR EXPLOSIVE POWDER.

Specification of Letters Patent.

Patented May 6, 1919.

Application led September 13, 1917. Serial No. 191,151.

My invention -consists of a box composed` of side, end, top and bottom pieces ofwood, battens at the joints of the end and side pieces `adapted to close the same tightly, and cleats at the joints of the top, end and side pieces adapted to close the same tightly, the box being designed more particularly for inclosing cans or canisters containing explosive powder which will not be endangered by concussione or blows on the box nor be liable to leak through the joints.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereofmay be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a perspective view of a box embodying my invention.

Fig. 2 represents a vertical section on the line 2 2 Fig. 1.

Fig. 3 represents a vertical section on the line 3--3 Fig. 1.

Similar numerals of reference indicate corresponding parts in the gures.

Referring to the drawings.

l designates the box, the same being constructed of the side pieces 2, end pieces `3, top piece 4, and bottom piece 5, saidseveral pieces being nailed to each other, the top piece 4: being secured in position to the upper portions of the side and end pieces by nails, as shown in Figs. 2 and 3.

The side pieces 2 are extended outwardly beyond the terminal portions of the end pieces 3 forming at what may be called the outside corners of the box, angular shoulders against which abut the battens 6 which are placed on the exterior of the terminal portions of the end pieces 3 of the box and extend in the vertical direction or height of the box and are secured to said pieces 3 by the nails 7. rlhen while the side pieces 2 reinforcing the box thereat, the battens also tightly closing the joints 0f the side and end pieces at their places of meeting, thus preventing leaking `of the contentsof the box through said joints.

Furthermore, the side pieces 2 and end pieces 3 of the box rest on the bottom piece 5 thereof, and the latter is secured to said pieces 2 and 3 by the nails 10, while the battens 6 are extended as at 11 below the bottoni edges of the side pieces 2 and 3, so as to rest againstv the adjacent edges or exterior of the bottom 5 to which they are secured by the nails 12, thus firmly securino,` the exterior of the bottom to the adjacent portions of the side and end pieces, and likewise to the battens. Then the lower ends of the battens will rest on a floor or place of location of the box, and so receive some of the thrust to which the bottom of the box is subjected, thus assisting the bottom piece 5 to endure the strain caused by said thrust.

The top piece 4L is sunken below the top edges of the side and end pieces 2 and 3, forming the depression 13 into which is received the cleats 14: which are` `placed against the inner facesof the adjacent portions of the side pieces 2, and have their ends abutting the inner faces of the adjacent portions of the end pieces 3, said cleats being connected with the top piece by the nails 15, thus serving to reinforce the connection of the top piece with the side pieces and causing the cleats to receive any inward thrust of the end pieces, preventing collapsion of the box, especially at the top.

.In the top piece is an opening which is occupied by the tubular neck 16 forming a spout or nozzle for the introduction of the powder into the can or canister 18 and the removal of the same therefrom, said spout or nozzle being provided with a closing cap 17 for evident purposes. In the use of the fastening devices for the respective parts which I term nails, I may substitute screws therefor, as may be desired. In the present case, the closing cap 17 is retained in position by a pin which is passed through the side rim of the cap into said nozzle, as shown most plainly in Fig. 2.

The box as made of wood will be found to be a poor conductor of heat and electricity, and so will insure the safety of the inclosed can which contains the explosive material,

and corner reinforcements, and the come parative integral nature ofthe entireconstruction of the body-'ofthe box, it being noticed that the top of said cap is at least iiush with the tops of said end pieces 3 and cleats 14, so that it does not project above said cleats and end pieces, whereby when boxes are piled one on the other the cap will not be subjected to downward pressure by the box above it, and the nozzle will not be crushed in, or the nozzle will not be i liable to be knocked off laterally by any blows that might be imparted to the side and end pieces, especially about the top portions thereof since its upper part occupies the space formed by the sunken top 4 and is surrounded by the upper portions of the end pieces 3 and the side cleats 14 as guards therefor.

When the members of the box are asseinbled and secured together the canister remains a fixture of the box leaving its nozzle in position to remove the contents ofthe canister, thc top piece not being intended to be removed to displace the canister, as the latter remains in the box as a stationary member therein adapting both the box and canister for further use in their entirety, the canister not being a removable member as such.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:-

l. A canister-inclosing box formed of'.

side pieces, end pieces, a top piece, a bottom piece, battens on the exterior corners of the box, and cleats on said top piece, said side and end pieces and top piece forming a sunken depression in the top of the box, all of said members being firmly connected, said cleats resting in said depression and having their terminal ends abutting the upper portions of the interior of said end pieces and having their outer sides abutting the upper portions of the interior of Isaid side pieces, said battens having` their lower portions extending below said side and end pieces and terminating at the bottom parallel Awith the underside of said bottoni piece and having their upper portion abutting the exterior of the end pieces and being overlapped by the inner faces of the terminal ends of said sido pieces.

2. A canister-inclosing box formed of side pieces, end pieces, a top pieve, a bottom piece, battens on the exterior corners of thc box, and cleats on said top piece, said side and end pieces and top piece formingl a sunken depression iii the top of the box. all

of said members being firmly connected, said cleats resting in said depression and haring their terminal ends abutting the upper por tion of the interior of said end pieces and having their outer sides abutting the upper portions of the interior of said side piewes. said battens having their lower portions extending below said side and end pievcs and terminating at the bottom parallel with the underside of said bottom piece and haring their upper portions abutting the exterior of the end pieces and being overlapped by tlie inner faces of the terminal ends of said side pieces, and a canister within said box having at the top a discharge spout which extends upwardly through the top piece into the depression thereof parallel or approximately parallel at the top with the tops of the members forming said depression.
